Hey

 

Where is the tick box to enable normal/bump map mode to be seamless? I'm getting lots of artifacts on top/bottom/edges of my maps!

 

Regards

Dariusz

Hey


Oh right I just noticed it. So it's an old feature since I guess 2014? Why is it still broken? Or does no1 use it because it's broken?

I know that your work around work. But if I have multiple maps with different details it will be very hard to manage after a while. If I have 15 specific texture in a layer that then need another 15 copies for fixing and so on. Seeing as processing of 16/32k at 16-32 bit depth maps can take a lot of time. Not only that why is there no profile settings to store/load for the actions?

Must say Adobe really know how to take out the "Pro" out of Photoshop and leave it just for moms retouching their exes out of pictures - sorry just angry and disappointed.


Hi

Why is it broken - it depends on the texture being used whether it will be visible, and even then whether the normal map is being tiled or just used once. Many use Photoshop for relatively simple work but turn to a proper 3D program for anything more serious. Photoshop is great for compositing 3D elements with 2D layers but is limited in its 3D capabilities.

Have you generated it from a layer that will tile seamlessly?

If not then it is easy to do :

Start with a square (or rectangular image) 4 with your intended map my example is 1024 x 1024

Use Filter- Other -Offset to move it half to the right and half down (in my case 512x512) and check wraparound

Use a brush or clone stamp to tidy up the edge joins which now run down the centre

Now it will tile so generate your bump/normal map and set the number or tiles you want to use in the dialogue

Hey

Thanks for idea Dave but my texture is 8k and 16k big with very fine details... I cant fix it by hand.

Is there really no Seamless option? Why did they release a normal/bump tool for Photoshop if we cant use it on textures?

Just to confirm it, my base layer is seamless. But when I do 3D>Normal thini I dont get seamless result

here is the screnschot of issue >

And another one:

Here is the procedure

4k texture

4k > to normal map

4k normal map > offset 2k each way

> result screenshot center of the image.

I'll get you an example.


Hi -

I don't see anything wrong with your process other than I would usually run an offset on the initial texture just to check it really is seamless.

If you can send the initial texture I will run the rest and post the result
